Fiberglass Grating

Fiberglass grating provides a strong surface for foot and some vehicle traffic while at the same time allows for ventilation and drainage. The framework of grating provides for both stability and openness. 

The fiberglass grating offered by Bedford has many inherent benefits, including corrosion resistance, low conductivity, fire retardance and is lighter and easier to handle than steel. It is engineered for strength and impact resistance, and an anti-skid surface helps prevent falls.

Fiberglass Grating Applications

Fiberglass grating can handle everything from foot traffic to ADA-compliant use to some heavy-duty vehicular traffic. The most common grating installations include:

  • Walkways
  • Platforms
  • Catwalks
  • Stairs
  • Ramps
  • Trench covers
  • Floor systems

The material is used by a wide range of industries, including water and wastewater treatment, oil and gas, cooling towers, plant and chemical processing, pulp and paper, mining, agriculture, theme and water parks, architecture, utilities, pedestrian bridges, construction, manufacturing and more.

Fiberglass Grating Types

Fiberglass grating can be molded or pultruded. Molded grating is generally a pattern of uniform square openings that create a mesh; these openings can also be rectangular. Pultruded grating is constructed of parallel bars connected by cross rods.

Molded grating is cast using interwoven fiberglass and resin, creating multi-directional strength. This strength allows for more customization and a wider range of application use than traditional single-directional grating. Popular panel sizes include 3' x 10', 4' x 8' and 4' x 12'. Bedford stocks these sizes and many more at multiple locations throughout the US.

Pultruded grating is created by pulling and shaping the fiberglass and resin into cross rods and bars with either an ‘I’ or ‘T’ profile. The bars are joined using cross rods perpendicular to the bars. The closer together the bars are, the stronger the grating, however it does not have multi-directional strength and is only strong in the direction of the bars. Pultruded grating can be used in longer spans.

Different resins and coatings offer benefits to specific applications of both molded and pultruded grating. 

Using the best fiberglass grating for the application ensures it will perform reliably for years, even in extreme conditions. Bedford’s fiberglass grating falls into six categories to meet your grating needs.

Frequently Asked Questions About Fiberglass Grating

What is fiberglass grating?
Fiberglass grating is a stable surface for foot and some vehicle traffic that allows for drainage and ventilation. Made of fiberglass and resin, fiberglass grating is light-weight, corrosion-resistant and high-strength.

How is fiberglass grating made?
Fiberglass grating is made by a molding or pultrusion process. Molded fiberglass grating is cast using interwoven fiberglass and resin. Pultruded fiberglass grating is made of bars and cross rods created through pultrusion.

How is grating measured?
Grating is measured by length, width and thickness. Grating specifications often include load and deflection amounts as well as the size and openness of the square grid.

What do you mean by grating?
Grating often means a lattice-like surface used for foot and vehicle traffic, as a partition, or as a covering.
